    No ECS Lights on Dash, Other Electrical Bugs

    Hey guys, I'm wondering where I should go next with this issue, here's the timeline of events:

    -Tour/sport light started flashing, so I unplugged the ecs computer.
    -Few days later I tried plugging the computer back in to see what it did just for kicks. No lights came on dash regarding ecs at all. I unplugged it again thinking it must just be the computer.
    -Checked under the front strut caps, one wire was broken, soldered it back together.
    -Replaced all the capacitors in the computer, some were fried.
    -Plugged unit in, still no lights regarding ecs on the dash at all.

    I've been searching and can't find any answers regarding if there's a dedicated (or otherwise) fuse for the ecs that could be checked. On another note my rear defrosters seemed to have stopped working recently but defrosters failed long after the ecs. Not sure if that could be in any way related or if they share a fuse. One other electrical bug is my interior dome light won't come on automatically when doors open with middle button depressed, but does work if I press the "on" button.

    I'm an electrical system noob - but I have successfully rebuilt my ECU and DCCD computers years ago.

    Thanks for any help, as I said I'm not sure where to go from here beyond swapping in a known good ecs computer... maybe somebody local has one available so I don't have to spend the money on a new one and possibly still not fix the issue.

    Thank you,
    Caleb

    My guess is your ECS computer is completely done. If the capacitors leaked all over the board they might have wrecked it all together. When mine went it did the same thing as yours, I replaced it with a known good working used unit and it works perfect now. I'm on brand new ECS struts all the way around, which could be another one of your issues. The struts themselves.
